BQ78PL114RGZT Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for high-frequency switching regulators, such as keeping the power stage components close together, using a solid ground plane, and minimizing trace lengths and widths.
  • The selection of the inductor depends on the specific application requirements, such as the output voltage, current, and frequency. Texas Instruments provides a list of recommended inductors in the datasheet, but it's also recommended to consult the inductor manufacturer's datasheet and to consider factors such as inductor core material, size, and saturation current.
  • The maximum ambient temperature for the BQ78PL114RGZT is 85°C, but it's recommended to derate the device's performance at higher temperatures to ensure reliable operation. Consult the datasheet for more information on thermal derating.
  • The BQ78PL114RGZT has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage source. The OVP threshold can be set by selecting the appropriate resistor values. Consult the datasheet for more information on OVP implementation.
  • The recommended input capacitor type is a ceramic capacitor with a value of 10uF to 22uF. The capacitor should be rated for the input voltage and have a low ESR to minimize voltage ripple and ensure stable operation.
